“OTHER PROGRAM SERVICES 4: Oklahoma State University, Improving Specifications to Resist Frost Damage in Modern Concrete Mixtures:This project seeks to produce improved specifications, and test methods, while improving the understanding of the underlying mechanisms of frost damage. The objectives of this project are:1) Determine the necessary properties of the air void system to provide satisfactory frost durability in laboratory testing of laboratory and field concretes with different combinations of admixtures, cements, and mixing temperatures in salt environments.2) Determine the accuracy of a simple field test method that measures air void system quality with field and laboratory concrete.3) Determine the critical combinations of absorption and the critical degree of saturation on the frost durability in accelerated laboratory testing in the presence of deicer salts.4) Establish new test methods and specifications for fresh and hardened concrete to determine frost durability and field performance. OTHER PROGRAM SERVICES 5: OTHER PROGRAM SERVICES 6: Improving Concrete Durability:Durability challenges, particularly with respect to quantifying freeze-thaw, salt scaling and alkali silica reaction (ASR), remain prevalent in the concrete industry. In an effort to further advance concrete durability, researchers at Oregon State University (OSU) and the University of New Brunswick (UNB) will utilize the groundbreaking modeling that has taken place at the Concrete Sustainability Hub (CSHub) at the Massachusetts Institute of Technology (MIT). The projects will examine new inputs and elements of ASR (UNB),salt scaling and freeze-thaw (OSU) and will include deliverables aimed at a better understanding of and the ability to control for durability challenges. Additionally, the experience and relationships of the researchers at OSU and UNB with other organizations will assist in the expansion of this knowledge/increased implementation as well as the potential for increased collaborative funding of future research. OTHER PROGRAM SERVICES 7: Evaluation of Deicer Impacts on Pervious Concrete & Development of a Deicer Testing Method for Pervious Concrete:There is strong evidence and instances that suggest certain de-icing chemicals and salts can negatively affect pervious concrete and initiate a rapid degradation of the paste matrix, aggregate bonding, pavement durability and strength. A number of project locations have reported a failure of pervious concrete pavements within the last year as a result of their exposures to deicers and salts in the very severe winter of 2013-2014. These instances suggest there is a required necessity to better understand what is causing this disintegration of pervious concrete paste when exposed to deicer chemicals and evaluate mitigations to modify pervious concrete mix designs to enhance paste characteristics and quality, and to be more resistant to these widely used chemicals.In order to better understand what has contributed to these failures and to adequately evaluate pervious concrete paste characteristics to withstand harsh deicer and salt applications, development of a standardized laboratory approach and process is necessary. This will require analysis to effectively and consistently: Determine the effect of various de-icing methodologies on pervious concrete, Define and understand the chemical relationship and reactions of deicers and salts on cement paste, and Research and evaluate the potential for improved resistance of different pervious concrete mixes to the deleterious effects of deicer methodologies in use. OTHER PROGRAM SERVICES 8: OTHER PROGRAM SERVICES 9: Evaluation of Chloride Limits for Reinforced Concrete - Phase I:This project has updated research from the 1980s for more modern concrete mixes that include recycled materials and other admixtures. The research includes the establishment of a relationship between total chlorides from the materials used for concrete and water soluble chlori”
